- Strong elasticity increases screw thread connection and reduces fatigue resistance issues by equalizing load across threads, compensating for pitch and tooth deviation between screw and hole, and absorbing vibration. - Anti-loose fit provides high reliability by preventing screw loosening, especially in applications demanding stable connections. - Ideal tool for screw thread removal: suitable for parts that require frequent disassembly, it improves service life and wear resistance of the screw thread. - Applies to thread insert connections and reduces thread insert damage: steel thread inserts used in low-strength materials such as aluminum and magnesium help avoid thread damage and improve connection strength and overall connection condition. - Applications: suitable for aluminum or magnesium components (eg, enclosures or housings), parts requiring frequent maintenance or disassembly (maintenance panels, access doors), and high-vibration or high-reliability machinery or automotive assemblies.
